Mechanical type delay switch

Abstract

The invention provides a mechanical type delay switch comprising a screw rod and two base plates fixedly mounted on two ends of the screw rod through an insulator; the screw rod and the base plates are made of a conductive material; the screw rod is in threaded connection with a nut member; at least two counterweights of the same weight are evenly distributed along the horizontal periphery and fixed outside the nut member; the nut member is enabled by the gravity effect of the counterweights so as to freely rotate downwards and slide on the screw rod; the counterweights and the nut member arerespectively made of a conductive material; the counterweights are electrically conducted with the screw rod through the nut member; when the nut member rotates to the end portion of the screw rod, the counterweights can make contact with the base plates on the end portion of the screw rod; one end portion of the screw rod is conductively connected with the first output electrode; the two base plates are connected in parallel through a wire, and conductively connected with the second output electrode. The mechanical type delay switch is simple in structure; each member can be mechanically processed for production; the mechanical type delay switch is suitable for production manufacture in a machining manufacturer.

Description

technical field [0001] The invention relates to the technical field of machining and manufacturing, in particular to a mechanical delay switch. Background technique [0002] Delay switches are widely used in many electromechanical control fields. But at present, most of the delay switches are realized by software control, or more accurate delay control is realized by means of electronic timers, which have the disadvantages of relatively complex structure and high technical requirements. However, in practical industrial applications, it is not necessary to perform very precise delay control in many cases, and only needs to have a delay on-off control function of several seconds to achieve simple delay control. At the same time, for some mechanical processing factories, they are usually not equipped with relevant production equipment and technical personnel for software control and electronic timer technology, so they cannot manufacture and produce delay switches with softwar...
